Santa Fe mayor joins anti-gun coalition

Coss and Police Chief Raymond Rael held a news conference Monday to announce their support.

Coss says he also plans to travel to Washington, D.C., on Wednesday to lobby with other mayors. More than 800 mayors across the nation belong to the organization called "Mayors Against Illegal Guns."

The group is pushing for criminal background checks on all gun sales, including private sales and sales at gun shows. They're also seeking renewal of a national ban on the sale of assault-style rifles and high-capacity magazines.

Santa Fe bought back nearly 200 weapons as part of its first gun buyback event on Saturday. The city is planning two more events in February and March.
